SOHIC - So What? NACE CORROSION OnePetro
Weband localized corrosion mechanisms, as well as environmental cracking mechanisms including, but not limited to, stress corrosion cracking (SCC), sulfide stress cracking … WebSOHIC can have a greater effect on serviceability than HIC because it effectively reduces load carrying capabilities to a greater degree. The inspection requires characterization of the defect areas to differentiate between spot inclusions, laminations, and different stages of hydrogen-induced cracking (HIC). Weblocalized nature of SOHIC. Keywords: hydrogen-assisted cracking; corrosion; SOHIC; cleavage fracture 1.
